This is an ominous statement...

"Many textbooks include exercises in which students are asked to determine the coefficients a, b, and c of a sinusoid of the form y = a*sin(b*x) + c or y = a*cos(b*x) + c. Such exercises are static, requiring the use of algebra, and often hold little appeal for students."

But the author does state the following as well...

"The objective is to actively involve students via the software simulations so that the determination of the sinusoidal model has a geometric flavor that complements the algebraic tools stressed in texts."

With regards to "modelling"...


It is hard to make a final judgement on this author's intent. The examples are well done, by a teacher that obviously knows both the visual AND analytical (algebraic) aspects of the material. However,
